Vantaggi
It's a steady job, and once you have learned the basics it is pretty easy. There is no element of needing to constantly make people happy, jump through hoops, or meet a changing sea of expectations. If you just got out of law school and haven't landed a job, this is a great opportunity - or if you're retirement age and looking for something to coast on, this is pretty decent as well.
Svantaggi
It's rote and repetitive, and there's limited positive human interaction. There are no colleagues or coworkers, and your supervisors are generally just there to make sure you're doing your job. While the work is remote, it is otherwise completely unflexible: You are scheduled to work a month in advance, so there's limited scheduling flexibility if something comes up that you had not planned for within that span of time. You're a neutral in the position akin to that of a judge, but also considered by the TWC to be working in a customer-service type role, so you have to deal with rude taxpayers with a smile (instead of being able into hold them in contempt). The workload is high, and you're locked down in one place for hours at a time very often. The workload is based on some amount of cancelled hearings, so that when people don't show up, you'll still be working to write decisions for the ones who did. If more people than not show up, you can readily become swamped.
